Install your eSIM step by step

Before your trip · install the eSIM

Use a stable Wi-Fi connection or hotspot. Your exact phone model must support eSIM and be unlocked for other operators.

1. 01

   Open your eSIM installation

   Connect the phone you will use for your eSIM to Wi-Fi. Choose one of the two options below. If this eSIM is already installed, skip to choosing the line for mobile data.

   The app or email on this phone

   In the Letisim app, open My eSIMs, choose your purchased eSIM and tap Install. On the preparation screen, tap Copy name and install.

   Or open your eSIM email on this same phone and tap Install eSIM. If the link opens your order page first, use the installation button shown there.

   A QR code on another screen

   Open your eSIM’s QR code from the email or order on a computer, tablet or another phone. Point the camera of the phone you are installing the eSIM on at the code, then tap the installation prompt.

   Both options lead to the phone’s system setup. Continue with step 2.

   The button or camera did not open setup?

   You can add the eSIM by scanning its QR code in Settings. Follow the path below, choose the QR scanner and use the code for your own purchase. If the QR is on this same phone, see the options without a second screen below the guide.

   Confirm installation on your phone

   The install button or your QR code opens the phone’s system setup. Confirm that you want to add the eSIM, then stay connected to Wi-Fi until the profile finishes downloading. If the phone first asks how to add an eSIM, use your QR code. You do not need to transfer your home SIM from another phone.

   Continue / Add / Install / Set up → wait for the eSIM to download

   Give the new line a clear name

   For example, “Letisim ”, so you can distinguish it from your home SIM. This is a label on your phone; it does not change the number or plan.

   iPhone: Settings → Cellular / Mobile Service → new eSIM → Cellular Plan Label → Custom

   Google Pixel / Android: Settings → Network & internet → SIMs → new eSIM → Edit name

   Samsung: Settings → Connections → SIM manager → new eSIM → Name

   Huawei: SIM management → SIM 2 → your eSIM → Card name. You can keep the existing label if no rename option is shown.

   Honor: SIM management → SIM 2 → eSIM name. Rename it if your MagicOS version offers this option.

   Xiaomi / Redmi: Manage eSIM → your plan → Change nickname, if available.

   Motorola: Open the new eSIM in SIM settings and use the edit-name option if available.

   OPPO: Open the installed profile in eSIM settings and change its label if your ColorOS version allows it.

   OnePlus: Open the installed eSIM and edit its name if the option is available.

   Line name: Letisim

   Check your connection

   Turn off Wi-Fi and open a map or website. If it loads, mobile data is working. If it does not, turn airplane mode on for about 30 seconds, turn it off and wait for a connection. Recheck the selected line and package settings.

   Wi-Fi off → website loads → you are connected
